Been trying to type comments in Youtube recently and every time I hit the "f" key, the video on the page goes to full screen. I don't know why this is happening. This does not happen with Google Chrome. I tried refreshing Firefox Nightly too but that did not work. For some reason, the problem happens on Firefox stable.

I believe I fixed it. Turns out I hit a key that switched to a certain mode for Firefox to use "f" key as a short-cut for full screen video. Is there a way to delete this?

There has been an issue with YouTube earlier today where certain keys always were interpreted as control keys that has been fixed by YT (YouTube reverted the change that caused this issue), so it shouldn't happen anymore. You may have to reload and bypass the cache (F5 or Ctrl+F5).
